Apple survey hints at iTunes streaming video service coming soon?

At this point we're fairly certain we'll see updated iPods at Apple's event on Wednesday, but we're still in the dark when it comes to that updated iOS-based Apple TV -- we know it's in the works, but we don't know if it's coming this week. But if you're feeling optimistic, a new Apple iTunes customer survey seems to offer a tiny little hint -- it lists "Titles are available to watch instantly" as a reason you might totally love watching video on the iPad. Of course, you can't watch iTunes videos "instantly" right now -- the iPad requires the entire video file to download before playback begins, and the current Apple TV requires a fair bit of buffering -- so this could be a big hint that instant streaming is coming quite soon. On the flipside, this could just be a mistake or oversight and actually mean nothing at all, but honestly, where's the fun in that?
